A seven amino acid fragment that opposes angiotensin II, studied in several conditions.
Effects studied or claimed
What it is used or promoted for, and where each effect has actually been seen
- Blood pressure loweringSmall human studies
- Lung injury, including COVID-19Small human studies
- Heart protectionAnimals
How it is thought to work
Angiotensin 1-7 acts on the Mas receptor to widen blood vessels and reduce inflammation, balancing the effects of angiotensin II.
What the evidence shows
Small human studies show effects on blood vessels. Trials in COVID-19 lung injury did not show clear benefit.
Safety and unknowns
Short half-life, and long-term safety has not been defined.
Regulatory status
